This is a lecture about chapter 11 of Russ ShaferLandau's book 'Whatever Happened to Good and Evil?' It deals with Moral Skepticism, Moral Nihilism, Moral Subjectivism, Moral Relativism, as well as the global versions of all of these views, which are selfdefeating. All of the uses of "Moral" are understood as equivalent to "Ethical". This lecture is part of an introductorylevel philosophy course, Introduction to Ethics.
